LOOM- SH UTTLE.

SPECIFICATION forming part of Letters Patent N 0. 686,555, dated November 12, 1901.

I Application filed January 9, 1901. Serial No. 42,611. (No model.)

To all whom it may cncern:

Be it known that I, DAVID SUSSMAN, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to shuttles for looms.

One of the'objects of the invention is to provide means adapted especially for use in connection with shuttles feeding out a plurality of threads for keeping said threads separated and lying side by side throughout the width of the warp instead of overlapping or twisting about each other, as is at present the tendency where a shuttle is made to feed out two or more threads.

Another object of the invention is to provide a simple, compact, and effective thread tension device for use in shuttles.

The invention is fully illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of a double-feed shuttle provided with an attachment for keeping the threads properly disposed and separated from each other and also with my improved tension device. Fig. 2 is a front view, somewhat enlarged, of said shuttle, certain parts being broken away. Fig. 3 is a perspective view of the batten, the shuttle provided with the above-mentioned attachment, and an auxiliary device to be used, if desired, to coact with said attachment in maintaining the threads in proper disposition and separated. Fig. 4 is a sectional view on the line w 00 in Fig. 1, and Fig. 5 is a perspective View of the improved tension device detached from the shuttle.

In said drawings, a designates the shuttle, the same having the usual quill-cavity b. In this cavity are arranged two or more quills c in the usual manner, the threads from said quills being adapted to be fed out of the shuttle through thread-eyelets cl, arranged in one of the side walls thereof.

Between each quill and the eyelets is arranged my improved tension device e. Essentially this device consists of a pair of reversely-disposed conical bars f. These bars may be mounted in somesuitable manner,with their ends secured directly in opposite walls of the shuttle; but it is'preferable that they be set in parallel walls 9 of a frame It. By giving the bars conical formand disposing them in reverse disposition the thread will obviously be kept at the middle portions of said bars, and so properly guided. In order to augment the action of the two conical bars, both as to properly guiding the thread and maintaining the desired tension thereon, I provide other bars 71, one each side of the conical bars and in alinement therewith. If desired, and with the object of varying the tension, the frame h, carrying these several bars, may be detachably arranged in the shuttle, several of these frames having difierent-sized bars, being kept on hand. The U shaped form of frame (shown inFig. 5) is preferable, because if it is properly made, so as to be somewhat elastic and slightly wider than the cavity of the shuttle, it may be forced into said cavity and held therein by virtue of its snugly fitting the same, at the same time being removable.

p j designates a substantially bow-shaped thread-guiding attachment which I secure to the side of the shuttle having the eyelets (1, preferably by screws k. This guide has a thread-eyelet Z, alined with the mindle eyelet cl and extending through said attachment toward its outer edge. The attachment shown has the form of a plate, and in its said outer edge is formed a groove m, with which the eyelet Z communicates. It is preferable that the two outer eyelets, d. be placed the one above and the other below the attachment j. The thread from one of the quills passes out of the shuttle through one of the two outer eyelets, whereas the thread from the other quill passes out of the shuttle through the eyelet Z, thence extending in one or the other direction from said eyelet along in the groove m. The attachment j may be constructed of any material, it only being essential that it have substantially the general contour shown in the drawings and be durable and preferably light in weight. If necessary, the shuttle may be provided with means for counterbalancing the attachment.

It will be seen that the attachmentj acts to keep the threads separated, not only because one thread is fed out at a point quite remote from where the other is fed out, but because since one of them lies in the groove m the initial points of their convergence are removed considerably away from the feeding out points. Of course the longer the shuttle and the narrower the goods the more appreciable will be the effect desired to be produced.

In order to further insure the maintaining of the threads separated, especially where the goods being produced is comparatively wide, I have provided an auxiliary device designed to interpose itself between the threads just after the shuttle leaves the box. This device consists of a finger 0, which is pivoted in a suitable portion of the loomsay the batten-said finger being adapted to be operated by a suitable moving part of the loom, so as to raise and lower to permit the shuttle to pass and interpose its point between the threads trailing from the shuttle.

I do not wish to be limited to the use of the attachment j in connection with shuttles adapted for two or more quills, for it is useful with a shuttle having but one quill, because since the groove on is not only appreciably remote from the thread-engaging point at the outlet of eyelet Z, but quite adjacent the end of the shuttle, it keeps the thread under control for a considerable distance from the latter or feeding-out point, and so augments maintaining it in proper disposition in the shed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a shuttle and a thread-guiding device carried thereby, the portion of said device remote from the shuttle having a thread-groove extending substantially lengthwise of the shuttle and from end to end of saiddevice, and said device also having a thread-eyelet communicating with said groove, substantially as described.

2. The combination of a shuttle and a thread-guiding device carried thereby, the portion of said device remote from the shuttle having a thread-groove extending substantially parallel with the shuttle, and said device also having a thread-eyelet communicating with said groove, substantially as described.

3. The combination of a shuttle adapted to feed out a plurality of threads and having a thread-eyelet in one of its walls, and a thread guiding device carried thereby, the portion of said device remote from the shuttle having a thread-groove extending substantially parallel with the shuttle, and said device also having a thread-eyelet communicating with said groove, substantially-as described.

4. In a thread tension device, the combination of a plurality of bars, and a plurality of other and reversely-disposed conical bars disposed between, and substantially in aline- .ment with, said first-named bars, substantially as described.

5. The combination, with a shuttle having a cavity therein, of a removable frame arranged in said cavity, a plurality of bars mounted in said frame, and a plurality of other and reversely-disposed conical bars also mounted in said frame between, and in alinement with, said first-named bars, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 29th day of December, 1900.

DAVID SUSSMAN.
